The double-acting LK piston sealing set is designed for installation in industry-specific grooves according to AS4716 (MIL-G-5514) and used in hydraulic and electromechanical actuators in aviation applications.
The LK piston sealing set consists of a PTFE piston sealing ring and an elastomer part which serves as a preloading element. Due to the material combination of the slide ring (PTFE) and the pre-loading element (elastomer), this product is suitable for a wide range of applications, especially for aggressive media and/or high and low temperatures.
Benefits:
• Can also be used for single-acting applications.
• Excellent wear resistance.
• Minimal break-away and dynamic friction and no stick-slip tendency ensures uniform motion even at low speeds.
• Good energy efficiency due to low friction.
• High temperature resistance in case of suitable compound selection.
• Installation in closed and undercut housings.
• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large compound selection for the elastomer pre-tensioning element.
• Dimensions according to AS4716 (MIL-G-5514).
